​Arsenal striker Pierre-Emerick Aubameyang has revealed that he is 'really frustrated' that he cannot be part of the Gunners' Europa League campaign and that the lack of regular games is the reason he is found it tricky to settle in at the North London club.

Aubameyang joined Arsenal in a club-record deal from Borussia Dortmund in January, however he cannot play any part in their Europa League campaign as his ex-club plays in the same competition this season.

Speaking to reporters regarding his frustration, Aubameyang told ​ESPN, "I am really frustrated because the rules are a bit... I don't know how to say in English, but I am disappointed because I can't help my team. That's life. I have to deal with it."

Aubameyang has ​scored three goals in the Premier League so far with two goals in his last two appearances for the Gunners. However, it's the longer breaks between games that has made it difficult to adjust to the pace of the English game.

He said, "When I was in Dortmund, I was playing every three days but now I play once a week or have a long time between games. It is not easy."

Concluding his interview, Aubameyang supported Arsene Wenger, who is under-fire for ​Arsenal's troubles this season. He said, "Of course I am really happy because I am here because of him. He had the interest in me so I am happy to play for him."
